that can be a hard request since so many names are not standard. my new instructor is an old school black belt, so most the time he has no idea the names i'm using for moves (he knows all the moves, just not the names i'm using).

funny example: i always call this move a genie armbar (from whatever position, not just this one)http://www.youtube.com/watch?v=oikWewjLG_U
because one of the main ways to finish it involves putting your hands on your elbows and crunching down, just like you're doing the "i dream of genie" wish motion. it's not until a few years of calling it this that i find out nobody outside my club calls it that.

best bet to get the most common name is to find the move on youtube and see what most people call it in their vids.
